исключение соединения RabbitMQ

Question

Я попытался использовать rabbitMQ, и при создании соединения я получил приведенное ниже исключение с выходом, я не уверен, что пошло не так. Завод работает нормально, и имя хоста, порт, имя пользователя и пароль устанавливаются правильно, но соединение прерывается каждый раз.

In main 
parametres setted , now creating the connection 
The host name and other params are localhost 
The host name and other params are admin 
The host name and other params are admin 
The host name and other params are 5672 
setted all the params

Answer 1

Я только что нашел решение этой проблемы. Я добавил файл common-io-2.5.jar в проект, и после его восстановления он работал.
